NTR, which is now focused on renewable energy and waste management, has reported a trading loss of almost €65m for the six months to the end of September. There was a small loss of €200,000 in the same period a year earlier.
The company said €41.6m of these losses came from spending on development of solar and wind energy projects.
Revenue was €205.4m, down 27% from a year earlier due to lower levels of activity in the waste management sector and its disposal of the West Link toll bridge in Dublin in 2008.
An interim dividend of just under 2.3 cent per share has been declared.
NTR said that during the period, it started construction of the 150 megawatt Lost Creek wind farm in Missouri and a solar project in Arizona.
The company said the performance of its Greenstar waste business had returned to levels experienced before the rapid decline in commodity prices a year ago, through a combination of cost cuts, organic growth and a recovery in commodity prices.
